Self hosted GitLab with a self-hosted LLM Provider connected to GitLab powering GitLab Duo. This should ensure that the data never gets outside your network, is never used in training data, and still allows you/staff to utilize LLMs. If you don’t want to self host an LLM, you could use something like Amazon Q, but then you’re trusting Amazon to do right by you.
